Commercial mountings for telescopic sights usually employ an elongated base plate that is mounted on the firearms receiver. The sight is supported by two mating pairs of half rings, mounted along the base plate. Some mountings support the sight in a raised position above the receiver so that the user can view the iron sights mounted on the firearm barrel without having to remove the telescopic sight.

SUMMARY OF THE INVENTION The broad purpose of the present invention is to provide a dual sight mounting having a pair of half rings connected together for supporting a telescopic sight, one of the rings having a pair of integrally connected, relatively movable walls which are clamped on opposite sides of the base plate in such a manner that the user can view the iron sights along a line of sight passing between the two walls.

Still further objects and advantages will become readily apparent to those skilled in the art to which the invention pertains upon reference to the following detailed description.

DESCRIPTION OF THE DRAWINGS The description refers to the accompanying drawings in which like reference characters refer to like parts throughout the several views and in which:

FIG. 1 is a perspective view of a rifle having a telescopic sight supported by a sight mounting illustrating the preferred embodiment of the invention;

FIG. 2 is a view of one of the sight supports of FIG. 1, with the telescopic sight removed for purposes of the description;

FIG. 3 is an exploded view of the support of FIG. 2;

and 1 FIG. 4 is an enlarged sectional view of the support of FIG. 2 showing the manner in which the base plate is clamped between the walls that define the opening for viewing the iron sights.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawing, FIG. 1 illustrates a conventional rifle having an elongated barrel 12. An iron sight 14 is mounted on the barrel. A telescopic sight 16 is supported by mounting means 18 on the receiver portion of barrel 12.

Mounting means 18 comprises an elongated base plate 20 and a pair of supports 22 and 24. Supports 22 and 24 are identical to one another and are mounted along base plate 20. Base plate 20 is connected by appropriate fasteners to the receiver of rifle 10.

Support 22, illustrated in FIG. 2, comprises a body 26 having a semicylindrical wall 28, and a pair of short coplanar walls 30 and 32 connected to the opposite side edges of wall 28. A half ring 34 is mounted on walls 30 6 and 32. Half ring 34 has a cylindrical portion 36 which cooperates with wall 28 to form an opening for receiving telescopic sight 16. Four set screws 38 connect the opposite sides of half ring 34 to walls 30 and 32 to clamp telescopic sight 16 to body 26.

A lower pair of substantially parallel spaced walls 40 and 42 are integrally connected to opposite sides of body 26. As best illustrated in FIG. 4, the lower edges of walls 40 and 42 have opposed V-shaped grooves 44 and 46 respectively mated with complimentary shaped ridges 48 and 50 formed along the longitudinal side edges of base plate 20.

Walls 40 and 42 are slightly flexible so as to be movable with respect to one another. An elongated threaded fastener 52 is mounted on the two walls as shown in FIG. 4 such that the user can clamp the base plate 20 between the two walls. Base plate 20 has a pair of openings 54 and 56 for receiving fastener 52 to locate body 26 with respect to the base plate. The opposite end of the base plate has a second pair of openings (not shown) for accommodating the fastener associated with support 24.

As best illustrated in FIG. 2, walls 40 and 42 support the telescopic sight in a position above barrel 12 so that the user can view iron sight 14 by a line of sight passing between the two walls. By forming the lower edges of walls 40 and 42 to mate with base plate 20, the telescopic sight can be readily attached to or removed from the rifle. In addition, the preferred embodiment of the invention employs only a single fastener 52 for connecting each support to the base plate. Thus the mounting assembly can be economically manufactured because it requires fewer components than other commercially available mounts.

Having described my invention, I claim:

1. In combination with a firearm having an iron sight mounted on an elongated barrel:

a telescopic sight;

base plate means mounted on the firearm, said base plate means having V-shaped longitudinal, parallel ridges along opposite sides thereof;

a pair of longitudinally spaced supports mounted on the base plate means, each support including a body having a semi-cylindrical wall for receiving the telescopic sight, and a pair of spaced side walls having upper edges integrally connected to the convex side of the semi-cylindrical wall, and lower edges with opposed V-shaped grooves mated with ridges of the base plate means, such that the semicylindrical wall is spaced above the base plate means to permit the user to view the iron sight along a line of sight between the base plate means and the telescopic sight;

a fastener connected to both side walls of each support adjacent the base plate means, the fastener being operative to move one of said side walls toward the other side wall to releasably clamp the base plate means between the lower edges of the side walls;

a half ring for each support, each half ring having its mid-section mounted on the telescopic sight adjacent the support, the means for connecting opposite sides of each half ring to opposite sides of each semi-cylindrical wall to prevent movement of the telescopic sight with respect to the supports.

2. A combination as defined in claim 1, in which the base plate means has a pair of openings aligned on opposite sides of the base plate means for receiving each fastener member.

3. A combination as defined in claim I, in which the side edges of the base plate means are adapted to slideably receive the opposed grooves of said parallel walls. 

1. In combination with a firearm having an iron sight mounted on an elongated barrel: a telescopic sight; base plate means mounted on the firearm, said base plate means having V-shaped longitudinal, parallel ridges along opposite sides thereof; a pair of longitudinally spaced supports mounted on the base plate means, each support including a body having a semicylindrical wall for receiving the telescopic sight, and a pair of spaced side walls having upper edges integrally connected to the convex side of the semi-cylindrical wall, and lower edges with opposed V-shaped grooves mated with ridges of the base plate means, such that the semi-cylindrical wall is spaced above the base plate means to permit the user to view the iron sight along a line of sight between the base plate means and the telescopic sight; a fastener connected to both side walls of each support adjacent the base plate means, the fastener being operative to move one of said side walls toward the other side wall to releasably clamp the base plate means between the lower edges of the side walls; a half ring for each support, each half ring having its midsection mounted on the telescopic sight adjacent the support, the means for connecting opposite sides of each half ring to opposite sides of each semi-cylindrical wall to prevent movement of the telescopic sight with respect to the supports.
 2. A combination as defined in claim 1, in which the base plate means has a pair of openings aligned on opposite sides of the base plate means for receiving each fastener member.
 3. A combination as defined in claim 1, in which the side edges of the base plate means are adapted to slideably receive the opposed grooves of said parallel walls.
